but that motor is a triple?

If someone started on making a cast oval port manifold in the same design but to suit the latest nissan micra engine HR12DDR supercharger unit it would match A12-A15 perfectly.

Those SC should become available from jap importers soon enough and available in time when such a manifold becomes available.

Could also suit a common AMR500 with different outlet bolt up holes already made into the design.

if that's from an MGB, I've just discovered it will bolt straight onto the J13 in my 520 teehee

times have changed SC are now under $500 each, SU $100 and manifold well just gotta make that then tuning.

I'm sure the pop-off valve could be modified to go to an external pipe without too much trouble. man 6 grand for a kit? I'mn just imagining that you could afford a good turbo setup and then have a few grand left over to build the engine for that. I suppose if you've got the money and you want S/C bad enough then go ahead and do it ;)

most superchargers have a pop off valve otherwise the backfire can turn from deflagration (a quick but controlled burn, just like normal engine combustion, and even in a firearm) - as pressures spike, into a full strength 'detonation' (a much more rapid and violent burn that will do significant damage)

FWIW there's been similar options (albeit with lysholm type compressors) to supercharge the mini a-series and bmc b series engines - done by 'link automotive' and 'hi performance products' (who are in the same street - thornton crescent in mitcham - or were the last time I looked)

They were around $5-6000 in the late 90's - no idea their price now. That was a full kit - charger, pulleys/tensioner/belt, intake manifold and SU carb (hif type iirc)

hope there is more than on D...

Im using a custom manifold I should finish it soon, it will have the manifold, amr500 and su all inline and angled 15 or 20 degrees to avoid puddling and consequently backfiring

Luv it, very neat

So the Anti-backfire valve is designed for blow-through, right? Using it as above is a kind of mistake?

D, you are planning on using the AMR500, can it be setup like this integrated with a manifold and SU?
